Yggdrasil Linux/GNU/X, or LGX (pronounced igg-drah-sill), was an early Linux distribution developed by Yggdrasil Computing, Incorporated, a company founded by Adam J. Richter in Berkeley, California.
Yggdrasil was the first company to create a Live CD Linux distribution. Yggdrasil Linux described itself as a "Plug-and-Play" Linux distribution, automatically configuring itself for the hardware.
The last release of Yggdrasil was in 1995.
Yggdrasil is the World Tree of Norse mythology. The name was chosen because Yggdrasil took disparate pieces of software and assembled them into a complete product. Yggdrasil's company motto was "Free Software For The Rest of Us".
Yggdrasil was compliant with the Unix Filesystem Hierarchy Standard.
